So on 2/18/05 I predicted that Google maps would add satellite images from their Keyhole company. Just two months later my prediction comes true: http://maps.google.com. The interface is very simple and allows you to either view the maps on google or the satellite images. The interface is fully functional between maps directions, and the drag-to-scroll behavior.
Next up, location based ads from their adwords department. I predict they will show small non-intrusive ads based on the location and subject that you search for.
